Have any of you had bad encounters with Geminis?

I am referring to both men and women. Sometimes it seems I am the only Cancer who feels this way as most I meet tend to love Geminis for some reason.

I have had a few bad run ins with Gems. Had a friend who turned into an Ex within 1.5 yrs. Bad gem bad bad. But I have a really awesome Gem friend whose one of my Best friends. The bad ones are full of themselves, lie, cheat, and steal. The good ones are like a damn brick wall, you know they will be there, they are genuine no shit type of people. Generally any straight forward person no matter what sign is appreciated (by me that is) And Gems are fun too! Always FUN!
